BUEiHlNG AND BUNG.

SPECIPICATIQN forming part of Letters Patent No. 327,509, dated October 6, 1885.

Application filed August 11, 1885. Serial No. 174,112. (No model.)

To on whom it may concern:

Be it known that I, ALBERT E. ALDRIDGE, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Bushing and Bung for Barrels, of which the following is a full, clear, and exact description.

This invention consists in a bushing and bung for barrels, of a bushing to be secured to a barrel, and a bung fitted to said bushing with suitable devices for securing the bushing to a barrel and for drawing the bung down into a seat in the bushing formed to receive it, to obtain a tight joint, and an annular groove or insulatingchamber or space, substantially as herein described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a vertical central sec tion through the bushing, showing the rubber packing in an annular groove formed in the bung, the bung being in elevation. Fig. 2 is a vertical central section through the bushing, showing the rubber packing supported in an annular groove formed in the bushing; Fig. 3, a top view or plan of the bung detached from the bushing, showing a central recess to receive a wrench to remove the bung from the bushing; Fig. 4, a perspective view showing the lower side of the bushing with its inclined planes and the bung with its lugs to draw the tapered surfaces of the bushing and bung together; Fig. 5, section of bushing, showing the annular insulating space or chamber.

A in the accompanying drawings represents a bushing for a bung, which consists of a hollow inverted frustum of a cone having a screw-thread on its outer surfa e o be screwed into a barrel in the usual manner of securing similar bushings.

To the inner surface of this inverted conically-shaped or tapered bushing A is fitted a bung, B, of the same taper as the bushing represented in Fig. 1, sov that when the tapering bung B is seated in the correspondinglytapered bushing A a tight joint between the bushing and bung will be obtained by drawing the two tapered surfaces snugly together. On the lower edge of this tapered bushing A to the safety of the bung.

are two inclined planes, G O, inclined in opposite directions, as shown in Fig. 4.

On the lower side of the bung B are two lugs, F, extending outwardly over the surface of the inclined planes 0 on the lower edge of the bushing, so that when the bung B is inserted into the bushing and resting in its seat therein, by a slight turning of the bung the lugs F thereon will ride upon the inclined planes Oand draw the two correspondingly-tapered surfaces of the bushing and the bung snugly together and maintain a tight joint between them. 7

In order to introduce the bung to its seat in the bushing, two perpendicular slots, E, are provided on the inner opposite surfaces of the bushing A,through which the lugs or proj ections F on the lower side of the bung are to pass, as shown in Fig. 4. These slots E also serve to receive a properly-fitted wrench by which to screw the bushing into a barrel, and to remove it therefrom when required.

The upper side of the bung B is recessed at P in the center, with square or irregularly shaped sides, to receive a correspondinglyshaped wrench with which to turn the bung in its seat to draw the tapered surfaces firmly together by means of the inclined planes 0 and lugs F,to secure the bung to the bushing and to render the joint between them tight,

and to remove the bung when required.

To further provide against leakage between the conical or tapered surfaces of the bushing and the bung, a rubber or other suitable packing, G, is introduced into an annular groove formed eitherin the bushing A, as shown in Fig. 2, or in a groove in the bung B, as represented in Fig. 1, whichever may be preferred, in such manner that when the bung is drawn down to its seat in the bushing by means of the inclined planes (land lugsFthe packing will be compressed between them to thoroughly pack the joint and thereby add much By grooving the bung to receive the packing G when the bung is removed to be cleansed and to refill the barrel,it is not necessary to remove the packing; but the bung and packing thereon may be cleansed together, thereby saving time and frequent loss of the packing. There being no shoulders either in the bushing or on the bung the bung is free to be drawn down into its seat in the bushing force required.

In order to prevent burning or charring the barrel by the heat of the pipes with which the hot air is introduced through the bushing to heat the inner surface when the barrel is intended to contain beer or ale, and thereby cause a leak between the bushing and barrel, the bushing A is provided with an annular recess or space, I, between the outer surface, which screws into the barrel and the inner tapered surface which forms the tapered seat of the bung. By this construction of the bushing the outer surface is insulated from the inner surface, with which the heated pipe comes in contact, and the barrel preserved from injury.

with any degree of Having thus described my invention,I claim as new and desire to secure'by Letters Patent- A bushing and hung for closing the bunghole in a barrel and other articles, constructed substantially as herein described and shown, consisting of a bushing, A, to be secured t a stave in a barrel, a bung, B, with suitable devices for uniting it with the bushing, and an annular space or chamber, I, in the bushing, as and for the purpose set forth.

ALBERT E. ALDRIDGE.
